Hi,
Just a quick question. i'm running some 10mm piros on some traywork. Is the bonding to the tray main bonding of supplementary bonding? The head is 3 phase rated at 200A but the piros are from a 3 phase ryefield board with 60A single phase supplies leaving to supply flats. I was advised by someone to fit a 4mm bond to the tray but this seems to be very small for it. I'm not sure how you go about sizing the bond for traywork and trunking???
Thanks for any advice.
